This is the two pack of JConcepts 6.5" Wide, High Down Force Wings. Debuted at the 2005 IFMAR World Championships, this wing design has been used successfully on medium to large sized tracks where quick rotation is necessary. The 6” wing has multiple gurney heights to adjust straight-line stability for all conditions and is marked and dimpled for quick mounting on the B4.1 and B44.1 buggies, but can also be fit to almost any 1/10th buggy available.
